Grapevine plant named Sugrafortythree

ABSTRACT

A new and distinct grapevine variety is characterized in that it produces a medium sized, broad, green ellipsoid berry with a large bunch size. The berries of ‘Sugrafortythree’ are firm and very juicy. The new variety ‘Sugrafortythree’ is characterized by a late ripening period and ripens most similarly to ‘Autumn King’ (U.S. Plant Pat. No. 16,284). In the Bakersfield, Calif. area the new variety ‘Sugrafortythree’ has a harvest start date of October 1 compared to September 15 th  for ‘Autumn King’.

LATIN NAME OF THE GENUS AND SPECIES CLAIMED

Vitis vinifera

VARIETY DENOMINATION

‘SUGRAFORTYTHREE’

BACKGROUND AND SUMMARY OF THE INVENTION

This invention relates to the discovery and asexual propagation of a new and distinct variety of grapevine, ‘Sugrafortythree’, as herein described and illustrated. The new variety was first hybridized in October 2010 by Terry A. Bacon in Wasco, Kern County, Calif. The variety was originated by controlled hybridization.

The new variety ‘Sugrafortythree’ is characterized by a late ripening period, the production of a medium sized, green and broad ellipsoid berry with a large bunch size. The berries of ‘Sugrafortythree’ are firm and very juicy.

The seed parent is the varietal selection ‘00061-153-466’ (unpatented) and the pollen parent is the varietal selection ‘Sugrathirtyone’ (U.S. Plant Pat. No. 19,065). The parent varieties were first crossed in May 2006 by Michael J. Striem. The date of first sowing was March 2007, and the date of first flowering was May 2010.

The new variety ‘Sugrafortythree’ was first asexually propagated in December 2009 in Wasco, Kern County, Calif., by Terry A. Bacon using hardwood cuttings.

The new variety ‘Sugrafortythree’ differs from its seed parent ‘00061-153-466’ (unpatented) in that the new variety ripens later, starting harvest about October 1^(st) compared to August 28^(th) for the seed parent.

The new variety ‘Sugrafortythree’ differs from its pollen parent ‘Sugrathirtyone’ (U.S. Plant Pat. No. 19,065) in that the new variety ripens later, starting harvest about October 1^(st) compared to August 23^(rd) for the pollen parent.

The new variety ‘Sugrafortythree’ ripens most closely to ‘Autumn King’ (U.S. Plant Pat. No. 16,284). In the Bakersfield, Calif. area ‘Autumn King’ has a harvest start date of September 15^(th) compared to October 1^(st) for the new variety. Additionally, the new variety ‘Sugrafortythree’ differs from ‘Autumn King’ (U.S. Plant Pat. No. 16,284) in that the berry weight of the new variety is less: 8.5 g compared to 11 g for ‘Autumn King’ (U.S. Plant Pat. No. 16,284).

The new ‘Sugrafortythree’ variety has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, cuttings.

Variations of the usual magnitude from the characteristics described herein may occur with changes in any of a variety of factors such as growing conditions, irrigation, fertilization, pruning, management and climatic variation.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new grape variety ‘Sugrafortythree’. The illustration shows the upper and lower surface of the leaves and exterior and sectional view of the fruit. The photographic illustration was taken shortly after the fruit was picked and the colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon the R.H.S. Colour Chart, published by The Royal Horticultural Society, London, England, 1986.

Many of the descriptive values in this specification are based on and conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997, which was developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV).

The descriptive matter which follows pertains to ‘Sugrafortythree’ plants grown in the vicinity of Wasco, Kern County, Calif. during 2013, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.
